Left Ventricular Mechanics in Multivessel Coronary Artery Disease with Versus Without Chronic Total Occlusion.
Article in Journal of cardiovascular development and disease, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Chronic total coronary occlusion (CTO) occurs within advanced coronary artery disease (CAD), but its association with left ventricular (LV) deformation and pressure-strain-loop-derived myocardial work beyond global LV ejection fraction (LVEF) is uncertain. We performed a retrospective cross-sectional analysis of 148 unique patients with multivessel or left-main CAD, including 70 with and 78 without CTO. Absolute global longitudinal strain (GLS) was the principal endpoint; global work index (GWI), constructive work (GCW), wasted work (GWW), and work efficiency (GWE) were secondary endpoints. Sequential CTO coefficients were estimated using HC3 heteroscedasticity-consistent linear models in a pool of patients with complete global mechanics and LVEF data. A history of myocardial infarction was more frequent with CTO (42.9% vs. 23.1%), with lower LVEF and larger LV volumes. In crude distributional comparisons among 136 patients with global mechanics data, median GLS was 14.0% versus 15.5% (
